Nitecore NL1834 3400mAh Rechargeable 18650 Battery

Hi, I have an issue with one of the batteries. I went to charge it, and nothing happened. The battery appears to be dead. I used 2 different chargers to be sure it wasn’t the charger. I was able to charge the others with no issue. Please help and advise, thanks

Battery fit perfect for my Ring Solar Path light.

they didn’t work for my surefire flashlight that uses two cr123a batt’s. i was told they would. i returned them & am going to order the cr123a batt’s individually (two needed & go from there.

Always buy my rechargeables from here. Excellent quality, well made, and durable.

Great battery. Lasts a long time.

Better than the rest!

This seems to be a high quality battery, but ended up being totally unsuitable for my application. I did not realize that because it has an integral protection circuit and also has a "button" on the + end, it is overall too long to fit into the battery socket. My complaint is not with this particular battery, but with Nitecore, whose website does little or nothing to point out that this product is longer than the standard 18650, and even the fact that it has the protection circuit is less than emphasized on the website. I called into Nitecore to point out how I had been disappointed and how I thought Nitecore could help others in the future in regard to this issue. The person I talked to could not have cared any less. I gave these cells away and will not use Nitecore again.

This is my forth battery which I use in two Nitecore flashlights and use the other two batteries as rotational backups.

Great batteries.

Now my flash light work

Great quality...always dependable

Great product this what I needed.

Great company , great products

Just what I needed to get my headlamp working again.

Perfect

Holds charge and lights brighter than it was.

Flashlight still dim light even after buying new battery and fully charging.

Great battery. Previous original last over 2 years in daily use. Still in service. This is extra for standby.

Great product!

This is my go to headlamp for tracking deer. The incredibly bright, white light is excellent for this job when you need to distinguish colors and moisture. After several years I needed to replace the battery. Seems to be working great again now. I've gone through many, many flashlights over the years. I'm a big fan of Nightcore's.
I also have one of Nightcore's extremely lightweight headlamps that I've used on the Appalachian Trail for nearly 350 miles.

Perfect for the ring solar path lights and the charger too. Saved a ton of money with these.

Received batterys promptly and in excellent condition. I put the battery's in my Nitecore 4 battery flashlight I have used for about 10:years (which lites up a lot of territory.) Great company and great products.

I bought 2 of these batteries for my Nitecore flashlights since my old ones finally went bad. So far so good. Charged them up completely like the instructions said and going strong. my flashlights are as bright as new like when i bought them. Id recommend the Nitecore brand batteries over the sketchy Amazon or Ebay ones any day.

Qualityas expected. Very satisfied customer.

These batteries are the best! So long lasting!

I'll buy more and also bought 2 MH12v2 flashlights and 5 batteries. Both seem to work very well.

Fantastic works as expected and I expect nothing less from Nightcore products fantastic will keep ordering from them battery was perfect size and everything my flashlight last forever now

Love it

Love this battery, it is a top-end battery for sure. Thank you very much.

NITECORE batteries are at another level. 1 of then looks like its leaking thou might have to ask for a replacement.

These are my go to for quality replacements. Very strong, long lasting batteries and hold a charge very well.
